The types used in GCC are intended to be consistent with what the libc's 
own headers do (lots of problems will arise if they aren't).  Newlib's 
headers, as of when this support was added to GCC, used long in that case, 
a use introduced by <https://sourceware.org/ml/newlib/2005/msg00824.html>, 
apparently because it was convenient for the newlib implementation at that 
time.
